Thebault-Spieker et al:

1 December 2015 - 12:54am
This article uses an interesting combination of quantitative and qualitative methods to shed light on decision-making among crowdworkers. The quantitative data demonstrated strong correlations between willingness to perform tasks and socio-economic status of the destination, while the qualitative data provided rather direct responses that implied causality. As far as the position of crowdsourcing on the […]

The Sharing Economy-Uber (Isaac 2015)

1 December 2015 - 12:37am
There is also a notable difference in the relationship between today’s two topics and GIScience as a discipline. While issues of scale are more clearly within GIScience, the sharing economy is one of those topics–along with, say, drones–where what’s most pertinent to discuss is how GIScience technologies (GPS, in this case) are employed, and what […]

Atkinson and Tate: links between scale and uncertainty

1 December 2015 - 12:02am
In this article, the authors discuss the problems associated with re-scaling data and possible tools for addressing these problems. Re-scaling is required in order to compare data sets that are collected at different scales. I find the article extremely dense and challenging, being very heavy on statistical theory, and the examples provided to give context […]

Problems of Scale in GIScience

30 November 2015 - 11:14pm
The topic of scale is a good example of GIS being synonymous with “doing science”. When I think about GIScience as opposed to GIS, I think about the problems that arise when trying to represent and communicate space using digital geographic information. Scale, as expressed in Spatial Scale Problems and Geostatistical Solutions: A Review by […]

Site Vs Situation

30 November 2015 - 8:25pm
In Thebault-Spieker et al.’s (2015) article they analyze the site and situation attributes of each census tract to get a better idea of the qualitative factors influencing crowdworkers decisions. They found that perceived safety and distance from starting location/accessibility both where the representative site and situation attributes. This got me thinking about the site and […]

Thebault-Spieker: Whose Crowdsourced Market?

30 November 2015 - 4:06pm
The authors situate mobile crowdsourcing markets such as TaskRabbit within geography, arguing that the geographical perspective is fundamental to the functioning of these markets. I was surprised by how little distance seemed to affect willingness to do a task: the authors write that workers were 4.3% less likely to do a task an hour away […]

Avoiding the South Side and the Suburbs: Thebault-Spieker et al., 2015

30 November 2015 - 2:59pm
Thebault-Spieker and colleagues (2015) discuss the geographic factors influencing mobile crowdsource market “workers” and how these factors may affect the willingness of a participant to accept a work task on the mobile crowdsourcing market application “TaskRabbit”. I found the article to be an interesting read, however I found that the authors could have made their […]

The Scale Issue in Social & Natural Sciences, Marceau 1999

30 November 2015 - 2:19pm
In Marceau’s piece, the issue of scale is discussed at length (no pun intended), and raises many good points. Scale and complexity truly go hand in hand, as complex systems can be invariant to scale (fractal characteristics) – a strange but intriguing phenomena. While the two topics are inherently linked, the issue of scale comes […]

Can we relate qualitative GIS and spatial scale? (Marceau)

30 November 2015 - 1:16pm
I found Marceau’s article to be a clear and easy-to-understand explanation of spatial scale, different frameworks of space and scale, and problems to do with spatial scale. I realized that I had really only thought of space, and therefore spatial scales, in the absolute sense, and I am looking forward to understanding the relative sense […]

Scale is an Issue!

30 November 2015 - 12:33pm
  As a student of the MSE and a frequenter of geography courses, my understanding of scale is far more developed than the average person’s (I hope). Marceau’s (1999) article was an interesting read because it forced me to consider, in depth, the problems beyond just noting MAUP as a point of contention in your […]

Marceau – Blurred lines

29 November 2015 - 6:17pm
This article emphasizes the importance of spatial scale in research and defines important concepts like space and scaling. Written in 1999, this article continues to be relevant to problems of scale presented by new technologies like drones. Marceau states “nor is a single scale sufficient to investigate phenomena that are inherently hierarchical in space.” She […]

Marceau’s Article

29 November 2015 - 3:56pm
Marceau’s (1999) article highlights what scale is and how it affects traditional (authoritative) geospatial datasets. This article reminded me of our discussion in Lesley’s geocomplexity seminar because Lesley addressed the concerns about being too specific or too generalizing, and whether or not we can have both. Marceau states research should explicitly state the variables, specifically […]

Isaac’s Uber Article

29 November 2015 - 3:52pm
Isaac’s (2014) article on Uber can certainly relate to our class discussions. Like Goodchild (2007) stated, spatially-aware technology like new smart phones have proliferated a series of location-based services, such as Uber. Moreover, Uber’s user-friendly applications allow amateurs to use Uber’s services, and also contribute to Uber’s services by classifying oneself as a contract worker. […]

UBER: Sharing Economy or Stealing Economy?

28 November 2015 - 10:24pm
This article uses the example of Uber to explicate the downsides of the so-called sharing economy . The author argues that Uber is another step towards the new neoliberal economy where employees have no job security or benefits. A depressed job market creates a steady supply of drivers willing to work and GIS technology enables […]

Goodchild (2007)-The brave new world of VGI

24 November 2015 - 12:52am
Goodchild’s very-well-cited paper on VGI from the mid-2000s is, among other things, a great example of prescience on the part of an academic–comprehensive (for 8 years ago), concisely-written, and representative of both specific knowledge in the evolving realm of GIScience as well as a general interest in the future of society as it becomes acquainted […]

Goodchild 2007: Are we human, or are we sensors?

24 November 2015 - 12:49am
VGI and citizen science is a recognition of the potential of mobilizing and utilizing ordinary citizens to aid scientific progress. It is the responsibility of the provider’s of technologies such as Open Street Map and Google Earth to dissolve the boundary between citizen and scientist in a way that preserves accuracy yet encourages involvement. In “Citizen’s […]

Drones: State of the technology (Watts)

24 November 2015 - 12:31am
Watts’ overview of drones is one of those “this is where we’re at right now” articles providing a closer look at the various categories of UAVs, their capabilities, advantages and drawbacks, etc. with regards to remote sensing applications. Watts claims that drones will spark a revolution in science similar to that of GIS, a claim […]

A Military History of Drone Use: An Aspiring GIScientist’s Analysis

23 November 2015 - 11:58pm
I am very intrigued by the Watts et. al’s brief history of drone use, mainly the concept of unmanned aircraft existing before the 20th century. This is a testament to the intrusive and all encompassing  influence of defense expenditure. More testament lies in the incredible variety of military drone technology described in this paper. I […]

Revolutionary VGI

23 November 2015 - 11:06pm
Elwood et al. (2013) investigate the potential research directions VGI can take in GIScience. They touch upon current problems with in VGI, including that of data quality control. As I began researching VGI for this week’s presentations, I quickly began to question aspects of its legitimacy. This stems mainly from my concern that the users […]

VGI: A disruptive force with room to grow

23 November 2015 - 10:48pm
In the chapter “Prospects for VGI Research and the Emerging Fourth Paradigm” Elwood, Goodchild, and Sui (2013) touch on important aspects of VGI such as quality concerns, types of engagement, and how it could evolve, especially in terms of coinciding with big data’s emergence. The differentiation between space and place as well as how the […]
